Transcutaneous electrostimulation for osteoarthritis of the knee: CAT

Abstract

Purpose. The aim of this CAT (Critically Appraised Topic) was to check the validity of the results and effectiveness of Transcutaneous Electrical Stimulation in subjects with knee osteoarthritis and answer the question: In subjects with osteoarthritis of the knee, does low frequency transcutaneous electrical stimulation reduce pain? Method. We conducted an analysis of the article "Transcutaneous Electrical Stimulation for osteoarthritis of the knee, Cochrane Systematic Review" of Rutjes et al (2009). We analyzed validity of results, applicability and effectiveness of this intervention in patients with knee osteoarthritis. Results. Low frequency transcutaneous electrical stimulation may reduce pain in subjects with knee osteoarthritis. SMD -0.85 (95% CI -1.36 to -0.34). Conclusion. The intervention is neither endorsed nor discouraged in knee pain reduction.
